California Governor Newsom and UK Forge Major Clean Energy Partnership Backed by Nearly $1 Billion in Octopus Energy Investment
Gavin Newsom signs transatlantic climate and clean technology accord with UK that opens markets, strengthens research ties and attracts Octopus Energy’s large climate tech commitment
California Governor Gavin Newsom has formalised a high-profile climate and clean energy partnership with the United Kingdom, underscoring subnational leadership in the global transition to low-carbon economies amid shifting federal policy dynamics.
In London on Monday, Newsom and UK Energy Secretary Ed Miliband signed a memorandum of understanding designed to deepen cooperation on climate action, clean energy innovation and nature protection, with a special emphasis on facilitating business linkages between California and British firms.
The accord, agreed during Newsom’s European engagement following the Munich Security Conference, is intended to boost transatlantic investment and research collaboration across emerging climate technologies such as offshore wind, solar, carbon removal and other clean-tech sectors.
It also aims to create new pathways for UK companies to access California’s extensive clean energy market, supporting skilled job opportunities and export potential for both economies.
A major private sector highlight of the strengthened ties is the nearly one billion dollars in clean technology investment by UK-based Octopus Energy into the Californian market.
Octopus Energy, already active in several states, plans to scale up its presence on the US west coast, deploying capital toward carbon removal, thermal battery systems and expanded renewable energy operations.
This commitment signals growing investor confidence in California’s policy environment and the economic opportunities offered by sustained climate innovation.
Newsom described California as “the best place in America to invest in a clean economy because we set clear goals and we deliver,” framing the partnership as evidence of the state’s capacity to turn ambition into substantive action on climate and energy.
Miliband emphasised that international collaboration would not only support emissions reduction but also “cut bills for families, reduce exposure to volatile fossil fuel markets and protect the natural environment,” while broadening export opportunities for UK firms.
The agreement comes at a moment when climate policy divisions at the federal level in the United States have drawn international attention.
California’s initiative reflects ongoing efforts by subnational leaders to sustain climate momentum despite national regulatory shifts.
By deepening ties with the United Kingdom and securing significant private investment, the partnership reinforces California’s role as a climate and clean technology leader and highlights the strategic value of cross-border cooperation in realising shared environmental and economic goals.
